When Mwonvuli Beast Tracker enters the battlefield, search your library for a creature card with deathtouch, hexproof, reach, or trample and reveal it. Shuffle your library and put that card on top of it.

Target creature you control gains hexproof until end of turn. You gain life equal to that creature's toughness. (A creature with hexproof can't be the target of spells or abilities your opponents control.)
